[android-developers] java.lang.IllegalStateException in Media.configure() with the new MediaCodec API

[David Hagege]

Hi,

I have a strange issue regarding the new MediaCodec API on Jellybean.
The native function android.media.MediaCodec.native_configure is throwing 
a java.lang.IllegalStateException.
I'm using the OMX.TI.DUCATI1.VIDEO.H264E codec on a Galaxy Nexus (maguro).

Here is my Scala code:


class ScreenshotView(context: Context, attr: AttributeSet, style: Int)
> extends SurfaceView(context, attr, style) with SurfaceHolder.Callback {
> private def startEncoder = {
> var surface = getHolder.getSurface
> var codec: MediaCodec = MediaCodec.createEncoderByType("video/avc")
>         codec.configure(MediaFormat.createVideoFormat("video/avc",
>           getWidth, getHeight), surface, null, 
> MediaCodec.CONFIGURE_FLAG_ENCODE)
>     }
> }

 



When calling the startEncoder method, the codec.configure() fails.
Here is what I can see in the logcat:

I/OMXClient( 1193): Using client-side OMX mux.
> E/OHELP   ( 1193): CODEC:android.media.MediaCodec@42124b70

If I'm looking at the JNI, here is where the exception is thrown 
(frameworks/base/media/jni/android_media_MediaCodec.cpp:338):


static jint throwExceptionAsNecessary(
        JNIEnv *env, status_t err, const char *msg = NULL) {
    if (err >= ERROR_DRM_WV_VENDOR_MIN && err <= ERROR_DRM_WV_VENDOR_MAX) {
        // We'll throw our custom MediaCodec.CryptoException
        throwCryptoException(env, err, msg);
        return 0;
    }
    switch (err) {
        case OK:
            return 0;
        case -EAGAIN:
            return DEQUEUE_INFO_TRY_AGAIN_LATER;
        case INFO_FORMAT_CHANGED:
            return DEQUEUE_INFO_OUTPUT_FORMAT_CHANGED;
        case INFO_OUTPUT_BUFFERS_CHANGED:
            return DEQUEUE_INFO_OUTPUT_BUFFERS_CHANGED;
        default:
        {
            jniThrowException(env, "java/lang/IllegalStateException", 
NULL);   /// I'm getting there                                     
            break;
        }
    }
    return 0;
}


This call is made in the last line of 
android_media_MediaCodec_native_configure() (line 389):

    err = codec->configure(format, surfaceTexture, crypto, flags);
>     throwExceptionAsNecessary(env, err);                                   
>                                          



Is there anything I'm doing wrong?
My surface is valid (isValid() is returning true). Everything passed to 
codec->configure() in the JNI seems to be ok too.
Any clues?

Thanks,
